1. The igniter (no more pilot takes the place of the pilot on newer furnaces) is bad and needs to replaced. 2. You have a dirty filter and the high temperature limit tripped the furnace to run the fan constantly without heat to cool the furnace. If the fan doses not shut down and allow the heat to start the limit may need to be reset. 3. The thermostat in the home maybe in the fan/on mode.
